Application filed July 5,

To all whom it may concern. Be it known that we, FRANK M. KINNAR and ROBERT M. KINNARD, both citizens of the United States, residing at Sebring, Mahoning County, Ohio, have invented a new Iand useful Spreader, of which the following is av specification.

This invention relates to spreaders for use in potteries for batting out clay, preparatory to placing the clay in the molds and more particularly to improvements over Letters Patent No. 1,430,309, issued September 26, 1922, to Frank yMrKinnard.

The patent referred toshows a spreader provided'with a bi-bladed spreader tool, a beveled block being provided upon each blade. While this tool performs the work in a satisfactory manner, it has been found by experience that the clay creeps or crawls up the beveled faces of the block and over the rear edges of the same,making itnecessary to stop the machine at frequent interivals to clean the accumulation ofclay from the tool.

The objects of the present invention are toprovide a spreader tool having a guard flange at the rear and side edges to prevent the clay from creeping or crawling over the same; to provide a four bladed tool upon the spreader; and to provide a spreader machine which is simple in construction and easily operated.

The above and other objects may be attained by constructing the machine as illustrated in the accompanying drawing, in which- Y Figure 1 is a longitudinal section of the spreader, embodying the invention, showing the same in the operative position; c

Fig. 2, a side elevation of the spreader tool Fig.V 3, a bottom plan view ofthe same; Fig. 4, a section on 'the 'line 4 4, F1g.'2; and

Fig. 5, a view similar to Fig. 4 of a slight modification of the tool.

Similar numerals of reference indicate corresponding parts throughout the draw-- ings.

The machine is mounted upon a base 1 at the forward end of which is located the usual block 2, which receives the ball of clay. Uprights 3 are mounted upon the base near the rear end thereof and support 1923. Serial No. 649,431.

adjustable vertically upon the base, as by the adjusting screws 5.

A sliding frame 6 is mounted upon the tracks d, being provided at its rear end with rollers 7, which extend into the channels of the tracks, rollers 8 being journaled at the forward ends of the tracks in position to support the frame 6. Y.

The sliding frame `is thus connected to the track only at its rear end, thus permitting the forward end of the same to be raised by means of a handle 9, tiltingthe frame upward upon the rollers 7 as upon a pivot, while the rollers 8 limit the downward movement of the frame, preventing the same from being lowered beyond the horizontal. v

A motor 10 is mounted upon the frame 6 and the Vshaft'll Vthereof is provided with a beveled pinion 12 meshing with a beveled gear 13 upon the vertical spindle 14 which is journaled in the bearings 15 and 16 upon the frame.

The spreader tool indicated generally by the numeral 17, is mounted upon the lower end ofthe spindle 14 and comprises the hub 18 having the radially disposed blades 19, each ofvwhich has the oppositely disposed lower beveled vedge 20. 'f

As shown inV Fig. 5 each' blade may ne provided with a wooden block 21 similar to the construction shown in the prior patent referred to, the under-surface of the block having the beveled face 22 which is preferably inclined at a greater angle to the horizontal than the beveled edge 2O or the blade. f

To prevent creeping or crawling of the clay up this inclined surface 22, a guard plate 23, preferably of sheet metal is vattached to the rear'face of the block'21 and it is also preferred to provide a similar guard plate 24 at the outer end.

In the construction shown in the other figures of the drawing, the wooden block is eliminated, the inclined beveled surface and the guard being formed integral from a metal plate or sheet 25 which is attached to the rear face of each blade and bent upwardly and rearwardly, as at 22a, forming the inclined surface corresponding to thev guard flange 23a While the side end of the plate is bent down forming the guard flange 24a'.

By thus inclining the surface 22 or 22a at a greater angle than the beveled edge v20ct the blade a clearance is provided and by forming the guard plate or flange at the upper rear extremity of the inclined surface, the clay will not crawl or creep beyondsaid guard plate, and it has been found from eX- perience that the spreader maybe operated continuously for an entire day` without the necessity of stoppingto clean the clay from the spreader tool, thus increasing the efficiency of the spreader considerably, and making it possible :for an operator to turn out afull days work' without the assistance of a helper.

The frame 6 when in the inoperative position is retracted within the tracks the rollers 7 upon the frame being ylocated atthe rear ends of the tracks, the stops 26 at the rear ends of thev tracks limiting the rear position of the frame, the forward end of the frame resting upon the rollers 8.

In order to operate the machine a ball of clay is placed upon the block 2 and the handle 9 of the frame is grasped, the frame being pulled toward the` operator and the forward end thereol2 raised sufficiently to permit the tool to clear the ball yof cla-y.

As the frame is pulled outward the vopperator lowers'the same to the horizontal position, the tool engaging the ball ofk clay and spreading the same into a flat shape as indicated at 27 in Fig; l.

The motor is operating continuously and a shield 28 may be provided to protect the operator from the spreader tool.

The spreader tool being rotatedupon an axis at right angles to the'normalfplane or the bloek2 forms a bat of uniforn'rthiclmess and smooth surface.

After the bat, as shown at 27, is formed, the frame is raisedslightly at its forward rnd to movethe tool out of engagement With the bat and the frame is pushed backward n the inoperative position to permit the operator to remove the finished bat and place another ball of clay upon the block 2.

lVe claim y l. A spreader including a slidablefframe, a rotatable spreader tool carried` thereby and means for rocking said frame.

2. A spreader including a horizontally slidable frame, a rotatable spreader tool carriedthereby and means for rocking said frame.

3. A spreader including a track, a frame mounted for sliding and rocking movement upon said track and a rotatable spreader tool carried by the frame.
